Application filed December 27, 1921. Serial No. 525,018.

This Invention relates to improvements in car construction.

In the operationof railroads, experience has demonstratedthat it ishighly advisable to so. connect the body and truck holsters of acar thatthey cannot separate vertically in event of rcollision `or derailmentsince this effectually prevents or V*minimizes .turning over ortelescoping of the cars. The use of suchv locking means is thereforegradually increasingand spreading to all classes'of cars.V No;,especial.diculty has been eX- perienced in applying proper locking means to carsemploying four-wheel trucks since 5 ample space is available beneath thepivotal or -king pin vconnection, of the bolsters. In the'case ofsix-wheel trucks however, and particularly dining, buffet and baggagecars, much diliiculty has been experienced in'applying any suitablet-ype of bolster locking device for the reason that the central axle oflthe six-wheel truck is located immediately belowthe pivotal center andit is impossible to obtain `access from above the bolsters through theycar floor on accountfof the lstoves or other fixtures ot the car beinglocated directly over the bolsters.

Furthermore, certain railroads prefer usim ing cast body bolsters havingacontinuous topy web over the king pin opening and hence in such carshaving six-wheel trucks, it is impossible to insert or withdrawvertically, a king pin of the locking type unless the truck ispractically completely dismantled for the purpose,.which is47prohibitive `from a practicalY standpoint.

vOne object of my invention is to provide a bolster locking connectionof an eicient Lio where access from above vor below the king pin openingis practically impossible.

Another object ofthe invention is the provision of an improved bolsterand king pin arrangement applicable to all conditions, to permitapplication of a king pin of either the usual type or of the lockingtype.

Other objects of the invention will more clearly appear from thedescription and claims hereinafter following.'

In the drawing forming a part of this specification, Figure 1 is avertical, transverse, sectional view of a car taken through the pivotalconnection of the body and truck holsters and showing my improvements inure 1.

type vand more particularly for those casesv connection therewith.Figure 2 isa longitudinal, vertical, sectionalv view corresponding tothe section line 2-2 of Figure l. And Figure 3 is a horizontal,sectional view corresponding to the section line 8-3jof F ig-I i In saiddrawing, the body bolster is indicated at A, the same being of the casttype and'having diaphragm sections 10-10, top web 11, integral bottomweb 12, vertical webs 13-13, and an integral center bearing section14C.y Rectangular opening l15` are formed within the body bolster toaccommodate a pair of vI-beam center sills 16--16 which are riveted tothe bolster as indicated at 17-*17. Y f 4' A cast truck bolster. C ofspider form'is shown, the same having a centrally disposed opening orsocket 18 of the contour best indicated in Figure 8 where it will benoted that the same is of generally rectangular form with outwardlycurved bulges 19-19 at the center. The socket 18 is adaptedto 'receive acorrespondingly shaped shank'20 formed integral' with an independent ordetachable center bearing section B having the top tace thereofconformed to cooperate with the under face of the body bolster centerbearing section 14. lThe shank 20 ofl the center bearing section B isdetachably se cured to the truck bolster C vby suitable means, .as forinstance the longitudinally ext-ending headed pins 21-21 which arepassed through alined openings in said shank and the web sections of thebolster C. Said pins 21 are held against accidentalremoval by cotters 22as clearly indicated in the drawing.

The center bearing sections v1K1 and B are provided with verticallyextending ali-ned openings 23--23 at their centers to accommodate alocking center pin which preferably consists of two outersemi-cylindrical sections 24-24 and an interposed spreader plate 25.Each of the pin sections 24 is provided at the top and bottom thereofwith laterally extended semi-cylindrical flanges 26-26 which overlie thecorresponding adjacent shoulders provided by the body bolster A and thelower edge of the detachable center bearing section B. The pin sections24 and the flanges thereofl are so made that the two sections areinsertable through the king pin openings when the spreader plate is notpresent and,-when the spreader plate is present, the parts willsubstantially fully occupy the king pin openings, thus locking the twocenter bearing sections together while at the same time treely allowingturning movements of the truck bolster with respect to the car body.

By reference to Figure l, it will be seen that the top web 11 of thebody bolster positively precludes the insertion or removal of a king pinfrom any point above the bolster. The same condition arises in the caseof holsters not having such a top web where the holsters are applied todining cars and certain other types of cars where the lixtures in thecar prevent the use of an opening through the floor. In Figure 2 ot thedrawing, the central axle ot the six-wheel truck is properly indicatedand it will be noted that the same is located immediately below the kingpin opening so that the insertionvor removal of the king pin from theunder side ot the truck bolster is thusprevented.

Vith my arrangement., it will be seen that the center bearing section Bmay be assembled and interlocked with the body bolster A independentlyof the truck and hence the latter may be run under the car body and thecenter bearing section B dropped into the socket of the truck bolster C.The final action is then obtained by inserting the pins 2l, as will beunderstood. In separating the truck trom the car body, the reverseprocedure takes place, as will be obvious.

With the arrangement shown, vertical separation ot the car body from thetruck is positively prevented, thus minimizing the damaging etl'ectsarising from derailment or wreck.

I have herein shown and described what I now consider the preferredmanner of carrying out the invention but I am aware that various changesand modifications may be made without departing from the spirit of theinvention. All such changes and moditications that come within the scopeot' the claims are contemplated.

I claim:

1. In car construction, the combination with a body bolster and a truckbolster, the body bolster' having a center bearing section permanentlyassociated therewith; of an independent center bearing sectioncooperable with said center bearing section ot' the body bolster', saidindependent center bearing section being rigidly but detachablyassociated with the truck bolster; and a center pin tor locking saidindependent bearing section and said body bolster center bearing sectionagainst vertical' separation while permitting relative rotationtherebetween, said center pin being detachable with reference to both ofsaid center bearing sections.

2. In car construction, the combination with a body bolster and a truckbolster, the body bolster having a center bearing section for lockingsaid independent center bearing section against accidental verticalseparation from the other center bearing section while at the same timeallowing relative rotation therebetween, said means extending throughboth said independent and said other center bearing sections and beingdetachable with reference to both of the same.

3; In car construction, the combination with a body and a truck bolster,said truck bolster having a centrally disposed vertically extendingsocket and the body bolster provided with a center hearing sectionrigidly associated therewith; ot' an opposed cooperable center bearingsection having a shank iitting within saidsocketV and detachably linedto the truck bolster.'

e. In car construction, the combination with a body and a trucklbolster, said truck bolster having a centrally disposed verticallyextending socket and the body bolster provided with a center bearingsection rigidly associated therewith; ot' an opposed cooperable centerbearing section havinga shank fitting within said socket and detachablylixed'to the truck bolster; and .detachable means for locking saiddetachable center bearing section against accidental vertical separationfrom the other center bearing section while at the same time allowingrelative rotation therebetweenb Y 5. In car construction, thecombination with a truck bolster having a vertically extending openingat the center thereof; of av center bearing section having-a verticallyextending member iitting rwithin said open` ing and detachably securedto said truck bolster and held against movement relatively thereto; anda body bolster having a cooperable center bearing section.

6. In car construction, the combinationwith a truck bolster; ot a centerbearing section rigidly but detachably connected to said bolster, saidcenter bearing litting within the truck bolster and having a horizontalstop shoulder coactingv with the latter.

7. In car construction, the combination with a truck bolster; ot anindependent center bearing section seated within the truck bolster andprovided with a horizontal stop shoulder engaging the latter; and meansfor detachably but rigidly connecting said center bearing section andbolster.

8. In a car having a body bolster,'the center oi which is inaccessiblefrom a point above the bolster, and a six-wheel truck in-A cluding atruck bolster and axle located below the center ot `the bolster, thecombination with a center bearing section detachably asbearing sociateclwith said truck bolster; and means for pivotally connecting said centerbearing section with the body bolster and preventlng verticalsepara-tion thereof.

9. In car construction, the combination with a cast body bolster havinga top Web at the center thereof and an integral center section; centersills extending through said bolster on opposite sides of the centerthereof; a truck bolster; and a center 10 bearing section detachablyconnected to said truck bolster.

In Witness that I claim the foregoing I have hereunto subscribed my namethis 12th day of December, 1921.
